Hi vz10, I'm pretty sure that the library can work on 4.1 too. For this, create a new 4.1 project and import the cs files shared by Paolo.

Hope that you will succeed.

Cool.

Did you switch to 4.3.1 ?

I have found that in 4.2.2 when building firmwares with yagarto gcc then the double.ToString function is not working properly due to some missing floating libraries in this compiler. I have planned to switch to 4.3.1 now, which use another gcc that have this support.

I also found that Graphics.featureproj was missing from my TinyCLR.proj file.

I like the video with the neopixels.

Any chance to share your code and hardware design with us ?

Hi All

 

I have  been able to build the Netduino Plus 2 firmware revision 4.2.2 with GCC yagarto tool using the wiki instructions, and I have discovered that the double.ToString API is not behaving as expected with this build. You can use the DFU file called myfirmware-forsanitycheck.dfu contained in the package provided in the wiki page in order to reproduce the issue I'm facing, as both the one provided and the one I have generated, behaves the same.

 

The following code snippet illustrate it :

            double dValue = 10.20;

            Debug.Print("-- value : " + dValue.ToString("F1"));

 

The expected result should be :

-- value : 10.2

but you get :

-- value : -545128520.00000000000000010

 

The strange thing is that the official 4.2.2 firmware (http://forums.netdui...2-firmware-v422) provided for the Netduino Plus 2 is behaving correctly.

 

So is anybody could give me some inputs to track down that issue and work on a fix ?

Is that could be related to : http://netmf.codeple...m/workitem/1385 ?

 

Thanks All

Hi DK

My guess was true, I have built a custom NetduinoPlus2 v4.2.2 firmware with the SPOT_Graphics in it and now I can display them to my panel.

I have enclosed the modified file in order to disable stub libraries and enable the real libs.

Note : it should also work on 4.3.1, but did not test it for now.

Enjoy!
